摘要 The preparation of the key intermediate 4 of the methyl isosar-tortuoate is described. The macrocyclization was completed through an intramolecular [2,3]-Wittig ring contraction. The four necessary stereogenic carbons were established by Sharp-less asymmetric AE and AD reaction. The preparation of the key intermediate 4 of the methyl isosar-tortuoate is described.
